LAMP-RECEPTACLE.

SPECIFICATION forming part of Letters Iatent No. 729,828, dated June 2, 1903.

Application iiled December 19, 1900.` Serial No. 40,401. (No model.)

To @ZZ whom, t may concern.'

Be it known that I, HERBERT C. WIET, a citizen of the United States,residing at Schenectady, in the county of Schenectady, State of New York, have invented certain new and useful Improvements in Lamp-Receptacles, of which the following is a specification.

My invention relates to sockets or recept-a cles for incandescent lamps or` attachingplugs; and its object is to provide a receptacle in which the terminals are concealed and yet can be easily gotten at for making connections with line-wires.

The invention consists in a base carrying the terminals and the screw-socket combined with a cover and locking-ring, as hereinafter set forth, and particularly pointed out in the claims. v

In the drawings, Figure 1 is a side elevation of my improved receptacle. Fig. 2 is a plan view thereof. Fig. 3 is a cross-section on line 3 3 of Fig. 2. Fig. 4 is a cross-section on line 4 4, Fig. 2.

The base A is of insulating material, such as porcelain. It has a iiat top and bottom, the latter being traversed by two parallel grooves ct for the line-wires. At the middle of the ridge between the grooves there is preferably a slight projection a', adjacent to which are lateral grooves a2 for the terminals.

Near each end of the base are holes n.3 for the attaching-screws. The terminals B B are of metal, their ends being slightly bent to fit across the grooves et' socket is preferably of sheet metal, with, a screw-thread rolled in it to iit the attachingplug or the base of alamp. At its upper end are two inwardly-projecting iiangesc, which lie between the horseshoe and the base. Screws c',passing through the base and flange into the horseshoe, secure the socketiirmly in place. When the lamp or attaching-plug is screwed into the screw-threaded socket, the terminals of said plug or lamp make contact With the terminals B B in the usual manner.

In order to conceal the terminals B B' and make a neat finish tothe receptacle, besides aifording a support to the socket, a cover D, of porcelain or the like, is provided, having a central hole to fit easily over the socket C.

`The cover may be of any desired shape; but

it is preferably circular, as shown. A locking-ring E, of porcelain or the like, is screwed upon the outside of the socket to retain the cover in place. The ring may be provided with a iiuted iiange e to give a better hold to the lingers and to improve its appearance. The ring is deep enough to conceal the socket, so that the entire receptacle appears to be made of porcelain or the like, the metal parts `being entirely inclosed.

What I claim as new, and desire to secure `by Letters Patent of the United States, is@- 1 ,A lamp-receptacle, comprising a base having transverse grooves, terminals lying across said grooves, a screw-threaded sheetmetal lamp-socket having flanges lying between one of said terminals and said base, a removable cover encircling the socket and extending over the grooves, and a locking `ring screwed upon the socket.

2. A lamp-receptacle' comprising the base A having on its face the side grooves ot a and the central projection ct', the terminals B B' HERBERT C. VIRT.
